ROMA hospital is next to be tested after traces of legionella were found throughout southern Queensland.
A total of 11 hospitals and outpatient facilities across Queensland have already confirmed presence of the bacteria.
After the death of a Brisbane cancer patient from legionnaire's disease at the Wesley Hospital earlier this month, testing began throughout the state.
The bacteria has been found at hospitals including Dalby and Toowoomba and at facilities in Miles, Taroom and Wandoan.
The south west has not had confirmation of any legionella bacteria however testing will commence across the region this week.
A South West Hospital and Health Service spokesperson said Roma Hospital, Westhaven and Waroona nursing homes, Charleville Hospital and St George Hospital will be included in the testing.
Acting Chief Health Officer Dr Stephen Lambert has called for calm as the results from more than 300 hospitals state-wide are being completed, analysed and collated.
"The handful of positive test results revealed over the weekend did not pose a risk to
human health and the infected sites or source of infection are easily treated," Dr Lambert said.
"We should not be speculating on interim low-level positive results until we know the full and final
picture for each facility."
Final results for hospitals and facilities in the south west region will be available from July 12.
